1. A nacelle for incorporation into a gas turbine engine, comprising: a nacelle having an inner wall defining a bypass duct, and an outer wall, at least one drive shaft extending through said inner wall, said at least one drive shaft to be connected to a gas turbine engine receiving the nacelle, said at least one drive shaft being connected to drive at least two accessory gear boxes, with said at least two accessory gear boxes being received between said inner and outer walls of said nacelle; andsaid at least two accessory gearboxes being circumferentially spaced; andsaid at least one drive shaft consists of one drive shaft driving both of said at least two accessory gearboxes via a first split shaft and a second split shaft within the nacelle. 2. The nacelle as set forth in claim 1, wherein at least one of said gear boxes includes a starter for the gas turbine engine. 3. The nacelle as set forth in claim 1, wherein at least one of said at least two gear boxes drives a fuel pump and a lubricant pump to support the gas turbine engine. 4. The nacelle as set forth in claim 1, wherein said at least two accessory gear boxes are received axially between an upstream end and a downstream end of said nacelle. 5. A gas turbine engine comprising: a fan, a compressor section, a combustor section, and a turbine section, said turbine section for driving a shaft to in turn drive said fan and said compressor, at least one accessory shaft to be connected for rotation with said turbine section;a nacelle having an inner wall defining a bypass duct receiving bypass air from said fan, and an outer wall, said at least one drive shaft extending through said inner wall, and being connected to drive at least two accessory gear boxes, with said at least two accessory gear boxes being received between said inner and outer walls of said nacelle; andsaid engine can be divided into two halves, and a mount bracket for mounting said engine to an aircraft is in one of the halves, and said at least two accessory gear boxes are in an opposed half; andsaid at least one drive shaft consists of one drive shaft driving both of said at least two accessory gearboxes via a first slit shaft and a second slit shaft within the nacelle. 6. The engine as set forth in claim 5, wherein at least one of said gear boxes includes a starter for the gas turbine engine. 7. The engine as set forth in claim 5, wherein at least one of said at least two gear boxes drives a fuel pump and a lubricant pump to support the gas turbine engine. 8. The engine as set forth in claim 5, wherein said at least two accessory gear boxes are received axially between an upstream end and a downstream end of said nacelle. 9. The engine as set forth in claim 5, wherein said at least two accessory gear boxes are circumferentially spaced. 10. A gas turbine engine comprising: a fan, a compressor section, a combustor section, and a turbine section, said turbine section for driving a shaft to in turn drive said fan and said compressor, at least one accessory shaft to be connected for rotation with said turbine section;a nacelle having an inner wall defining a bypass duct receiving bypass air from said fan, and an outer wall, said at least one drive shaft extending through said inner wall, and being connected to drive at least two accessory gear boxes, with said at least two accessory gear boxes being received between said inner and outer walls of said nacelle;at least one of said gear boxes includes a starter for the gas turbine engine;at least another of said at least two gear boxes drives a fuel pump and a lubricant pump to support the gas turbine engine;said at least two accessory gear boxes are received axially between an upstream end and a downstream end of said nacelle; andsaid engine can be divided into two halves, and a mount bracket for mounting said engine to an aircraft is in one of the halves, and said at least two accessory gear boxes are in an opposed half; andsaid at least one drive shaft consists of one drive shaft driving both of said at least two accessory gearboxes via a first split shaft and a second split shaft within the nacelle. 11. The engine as set forth in claim 10, wherein said at least two accessory gear boxes are circumferentially spaced.
